An uncomfortable, persistent itch on your legs, ankles, or feet could be a crucial warning sign of diabetes, a lifelong condition impacting millions across the United Kingdom. Health experts are urging the public to be aware of this and other key symptoms to enable early diagnosis and management.
Itchy Skin: A Common Diabetes Complication
According to medical resources, including Diabetes.co.uk, itchy skin, particularly on the lower limbs, is a "common" complication of diabetes. The condition, which causes blood sugar levels to become too high, can manifest in two primary forms: type 1 and type 2. While the exact cause of type 1 is unknown, type 2 is frequently linked to factors such as being overweight, insufficient exercise, and genetics.
"Itchy skin can be a sign of diabetes, particularly if other diabetes symptoms are also present," explains Diabetes.co.uk. The itching is often a direct result of prolonged periods of high blood sugar or can stem from diabetes-related complications like nerve damage or kidney disease. The sensation can vary from mildly annoying to severely disruptive, but it may be relieved or eliminated by treating the underlying cause.
Expert Backing and Skin Rash Risks
This guidance is strongly supported by specialists at the renowned Cleveland Clinic. They state that approximately one in three people with diabetes will encounter a skin rash or related issue. For those without a diagnosis, a new skin rash could be an early indicator of high blood sugar (hyperglycaemia) or prediabetes.
The clinic's experts note: "When you have diabetes, your chances of having dry, itchy skin are higher than someone who doesn’t have the disease." They also highlight that a rash in someone already undergoing treatment might signal a need to adjust medications to better control glucose levels. Some rashes are a consequence of reduced blood flow to the hands and feet.
Recognising Other Key Symptoms
Spotting diabetes early is vital, as both main types can be managed with appropriate treatment. Alongside persistent itching, the NHS lists several other common symptoms to watch for:
- Feeling excessively tired
- Urinating more frequently than usual, particularly at night
- Experiencing constant thirst
- Losing weight without trying
- Having blurred vision
- Cuts or wounds that take longer to heal
- Itching around the penis or vagina, or recurring bouts of thrush
It is estimated that more than 5.8 million people in the UK are currently living with diabetes. If you or someone you know is experiencing any combination of these symptoms, it is crucial to speak to a GP for advice and possible testing. Early intervention can help prevent serious long-term health complications.
